errors on e-mail merge

When attempting to do an email merge (either single contact or several), I keep getting 2 error message boxes, an ACT error message box which says "A dialog box is open, close it and try again", and another Internet Explorer error box which says "One or more Active X controls could not be displayed" I am using ACT 2007 single user, and MS Word as my Act word processor.
